AC Weirdness

[Eyvind Spangen]

Can be a low R134a charge. The pressure on the low pressure side of the 
system will drop too low after a few seconds with the compressor running. 
Then the low pressure cutout switch will turn the compressor off, the 
pressure will even out somewhat between the high and low side, and it will 
turn back on. This will repeat over and over and over. BTDT on a '87 5k and 
'94 S4. A recharge fixed the problem, at least for 1 and 2 years, the time I 
owned the cars after the recharge.
